TornadoVM v0.15.1

Date: 15/05/2023

Improvements

• Introduction of a device selection heuristic based on the computing capabilities of devices. TornadoVM selects, as the default device, the fastest device based on its computing capability.
• Optimisation of removing redundant data copies for Read-Only and Write-Only buffers from between the host (CPU) and the device (GPU) based on the Tornado Data Flow Graph.
• New installation script for TornadoVM.
• Option to dump the TornadoVM bytecodes for the unit tests.
• Full debug option improved. Use --fullDebug.

Compatibility/Integration

• Integration and compatibility with the Graal 22.3.2 JIT Compiler.
• Improved compatibility with Apple M1 and Apple M2 through the OpenCL Backend.
• GraalVM/Truffle programs integration improved. Use --truffle in the tornado script to run guest programs with Truffle.
  Example: tornado --truffle python myProgram.py
  Full documentation: https://tornadovm.readthedocs.io/en/latest/truffle-languages.html

Bug fixes:

• Documentation that resets the device's memory: https://github.com/beehive-lab/TornadoVM/blob/master/tornado-api/src/main/java/uk/ac/manchester/tornado/api/TornadoExecutionPlan.java#L282
• Append the Java CLASSPATH to the cp option from the tornado script.
• Dependency fixed for the cmake-maven plugin fixed for ARM-64 arch.
• Fixed the automatic installation for Apple M1/M2 and ARM-64 and NVIDIA Jetson nano computing systems.
• Integration with IGV fixed. Use the --igv option for the tornado and tornado-test scripts.
